HYDROSlPHON-VALVE FOR WATER-HEATERS.

SPECIFICATION forming part of Letters Patent No. 773,687, dated November1, 1904. Application filed February 11, 1904. Serial N0.193,130- (Nomodel.)

To all whmn it may concern:

Be it known that I, J AMES A. STEVENSON, a citizen of the United States,residing atNewcastle, in the county of Lawrence and State ofPennsylvania, have invented certain new and useful Improvements inHydrosiphon- Valves for ater-Heaters, of which the following is aspecification.

My invention relates to a new and useful process for heating the waterin a boiler or tank, whereby quicker results are obtained and a materialsaving in the amount of fuel required to heat a given amount of water isaccomplished.

My invention consists in the novel arrangement of inlet and outlet pipeswith relation to the boiler in connection with the regulating deviceillustrated in the accompanying drawings, forming a part of thisspecification, in which- Figure 1 is a vertical side view of an ordinarydwelling-house boiler, showing the arrangement of the pipes leading toand from the same, together with a heating device. Fig. 2 is ahorizontal sectional view of the siphon-valve I employ in thesupply-pipe to prevent the water in the bottom of the boiler fromescaping back and mixing with the heated water being drawn off throughthe hot-water spigot.

The numerals of reference designate like parts throughout the severalviews, in which The numeral 1 is the boiler, and 2 the stand supportingthe same.

3 is the cold-water inflow or supply pipe connected with the three-waysiphon-valve joint 5, on the inside of which is formed the nozzle-shapedportion 6 and reduced opening 7 the two together forming a siphon.

8 is a straightway passage formed in the perpendicular upright of thejoint.

9 is a pipe connecting the pipe 3 with the under side of the boiler.

10 is a pipe leading from the top of the boiler and connected with thepipe 10,which leads to the coil or any ordinary heating device 11.

12 is an ordinary burner.

13 is a three-way connecting-joint affording a straightway passage fromthe heating device to the siphon-valve connection at 8 and to thehot-water-outfiow pipe 14:.

The arrangement of pipes and connections shown in Fig. 1 is made toillustrate the means employed to facilitate heating the water in theboiler in an economical and speedy manner in connection with mysiphon-valve shown in Fig. 2.

By means of the siphon-valve aforesaid I can obtain a greater amount ofheated water in much less time than is now necessary by the methods incommon use in the following manner: The boiler being first tilled withwater through the supply-pipes 3 and 9, heat is generated below the coil11 and the water rises therein and in pipe 10, passing through pipe 10to the boiler and down through the latter and past the siphon-valve andT 13 into coil 11. This circulation is continued as long as the heat isgenerated while no water is drawn. The instant the Warm-water spigot isopened the course of circulation is reversed, and the cold water in thesupply-pipe 3, taking the place of that drawn olf, begins to siphonthrough the valve 5 and forces the water undera pressure from thenozzleshaped portion 6 through the reduced opening into the pipe 9 andthence into the boiler. The force of the water through the nozzle-shapedportion 6 and into the reduced opening 7 will prevent any Water from thebottom of the boiler escaping back through the siphon-valve 5 andmingling with the heated Water being drawn off through the outlet-pipe14:. It will therefore readily be seen that only the preheated Waterfrom the boiler will be drawn off at the hot-water spigot while theboiler is being refilled through the siphon-valve and connecting pipes.

Having thus fully shown and described my invention, what I claim as new,and desire to secure by Letters Patent, is-

1. In a water-heater of the character de' scribed, a boiler, asupply-pipe leading thereto, a three-Way siphon-valve having a nozzleportion and a reduced portion oppositely disposed thereto, connectedwith said supplypipe, a pipe mounted in the top of the boiler, a heatingdevice connected with the lasting member forming a straightway passagefrom the heater to the siphon-valve and an outlet-pipe leading from thethree-Way connection, substantially as described.

In testimony whereof I aifix my signature in presence of two witnesses.

JAMES A. STEVENSON.
